TCM809 General Description

The TCM809 and TCM810 are cost-effective system supervisor circuits designed to monitor V_CC in digital systems and provide a reset signal to the host processor when necessary. No external components are required.

The reset output is driven active within 20msec of V_CC falling through the reset voltage threshold. Reset is maintained active for a minimum of 140msec after V_CC rises above the reset threshold. The TCM810 has an active-high reset output while the TCM809 has an active-low reset output. The output of the TCM809 is guaranteed valid down to V_CC = 1V. Both devices are available in a SOT-23B-3 package.

The TCM809/810 are optimized to reject fast transient glitches on the V_CC line. Low supply current of 17mA (V_CC = 3.3V) makes these devices suitable for battery powered applications.
